Perhaps you should try some spelling variations:
"effects sampling algorithm" » "effects mining algorithm" (Expand Search), "effects modeling algorithm" (Expand Search), "effects along algorithm" (Expand Search), "effects arising algorithm" (Expand Search)
"elements ree algorithm" » "elements tree algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements rf algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements present algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"elements em algorithm" » "elements new algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements ppm algorithm" (Expand Search), "elements res algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements ree algorithm") OR ("elements em algorithm"))) OR ("effects sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements ree algorithm\") OR (\"elements em algorithm\"))) OR (\"effects sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements ree algorithm ) OR ( elements em algorithm ))) OR ( effects sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements ree algorithm") OR ("elements em algorithm"))) OR ("effects sampling algorithm"))*.
